MANUFACTURING CIGARS.

Application filed May 14, 1927, Serial No. 191,547, and in Germany May31, 1926.

This invention refers broadly to the manufacture of cigars, and it-isparticularly 1ntended to pg'ovide means of manufacturing superior gradesof cigars by avoiding the difliculties heretofore encountered byproviding the cigar with a high grade outer wrapper or cover. In themanufacture of cigars as generally practiced the tobacco is enclosed inthe so called cigar-roll com prising the filler and the cover and thisroll is then surrounded by the so called wrapping leaf or wrapper. Thepositioning of the wrapper, which in most cases has to be effected bymanual operation, is a very tedious and expensive class of work,requiring a high degree of dexterity and skill; and inasmuch as thewrappers are made from the best and healthiest leaves, any wasteoccurring in this operation can only. be used as a filler and,therefore, cause loss to the manufacturer. I Even where application ofthe wrapper is effected by machinery losses of material in applying thevaluable wrapping leaves can not be avoided. Nor has it been possible tosimplify and facilitate the operation of applying the wrapper byutilizing the so called tobacco-paper obtained. as an artificialproduct.

These difliculties are overcome by my invention which makes it possibleto provide the cigars with a durable but comparatively inexpensivewrapper which may be applied either by machinery or by hand. Accordingto this invention tobacco leaves which, both as regards their color andodor, are suitable for use as wrapping leaves, but which need not be anyparticularly selected leaves, are very'finely subdivided and aresuspended in this condition in a liquid containing a suitablecombustible bindlng agent, the more or less pasty material thus,obtained being applied to the cigar-roll.

The accompanying drawing is a view partly inelevation and partly inlongitudinal section of a cigar having a wrapper produced according tomy invention.

As a liquid suitable for the purpose of this inventlon I may employ, forexample, a

. varnish which will not affect the palatability and the burning of thecigar, such as a solution of a cellulose-ester, preferably theacetyl-ester of cellulose. As a solvent. a liquid is used which willreadily evaporate and does not have any-objectionable influence upon thecigars. The suspended matter comprising the paste of tobacco powder .andapplied to the cigar roll produces a firmly adhering, permanent coatupon the roll after the evaporation of the solvent and which willperform the' same function as the wrapper heretofore employed. Theapplication of the suspended matter onto the cigar roll may be effectedin different ways,

and sometimes even a better, taste and are more readily combustible thanordinary cigars. The manufacture is considerably simplified andcheapened; and the very serious losses heretofore incurred in theapplication of the valuable wrapping leaves are avoided by theemployment of the novel kind of covering wrapper.

As a means of suspending the tobacco powder use may be made of solutionsof suitable resins or-artificial resins or resin-esters. The suspendedtobacco material may also be mixed with the well known additionsordinarily employed for the manufacture of cigars to be smoked for therelief of asthma such as, for instance, the powdered leaves ofstramonium or thorn-apple. 1

It has already been suggested to replace the usual cigarette paper bythin foils obtained from solutions of cellulose esters with the additionof cigarette tobacco. My invention is distinguished from this byproviding means of doing away with the employment of natural orartificially prepared special wrappers with the accompanying tedi 1s andvery expensive application of the wrapper, which step is not encounteredin the manufacture of, cigarettes. In accordance with this inventionthewrapper is produced directly on the'cigar roll itself by theevaporation of the solvent, and this feature and the resultingpossibility of' manufacturing large quantities of cigars on amanufacturing scale constitutes one of the important objects andadvantages of the invention. There is the other important improvementthat it is no longer necessary to employonly specially selected valuablewrap-- vantages are of coursenot necessary in connection wlth themanufacture of cigarettes. The method of treatment herein descrlbed issusceptible of being modified and altered.

in accordance with the convenience of the user and other conditions anddifferent solvents and other materials may be employed without therebysacrificing the main features of the invention as particularly pointedout in the appended claims.

I claim 1. The methodof manufacturing cigars, which consists insuspending tobacco powder in a liquid containinga combustible bindingagent and applying the resulting pasty mixture to the-core of cigars.

2. The method of manufacturing cigars,

which consists in suspending tobacco powder in a mixture of a llquidbinding agent with a volatile solvent and applying said mixture to acigar-core, allowing the solvent to evaporate, and thereby forming afirmly adhering coating of tobacco upon said core.

3. The method of manufacturing cigars, which consists in suspendingtobacco powder a liquid containing a solution of a cellulose ester andapplying the mixture obtained to a cigarcore and allowing the apester,applying the mixture obtained to a.

cigar-core and allowing the applied matter to dry in contact with saidcore.

5 As a new article of manufacture a cigar comprising a core and awrapper formedthereon by a dried and solidified coating of a solution ofa cellulose ester and comminuted tobacco leaves incorporated therewith.i

6. As a new article of manufacture a cigar comprising a core and -awrapper formed on said core by a dried and solidified solution of acellulose-acetyl-ester with comminuted tobacco leaves incorporatedtherewith.

In testimony whereof I have signed my name to this specification. is
